CONSTRUCTION OF BUILDINGS.

SPECIFICATION forming part of Letters .Patent No. 718,429, dated January13, 1903.

To all whom, it may concern:

Be it known that l, HENRY D. CONWAY, a citizen of the United States,residing at .I ackson, in the county of Jackson. and State of Michigan,haveinvented certain new and useful Improvements in Construction ofBuildings and I do hereby declare the following to be a full,clear, andexact description ofthe invention, such as will enable Others skilled inthe art to which it'appertains to make and use the same.

tures of the invention.

This invention has relation chiefly to lireproof structures-such asdwellings, officebuildings, assembly-halls, and the like-and aims tosimplify and cheapenV the construction of buildings of the characteraforesaid, as well as to increase their strength and durability. Y

Aln accordance with this invention a form is set up and the spacebetween the sides is filled with cement, which when set and hard isself-supporting and constitutes the walls ofv the structure. The formcontemplates molds for exterior and interior decoration and finish, suchas the cornice, panels,'moldings and trimmings around Window, door, andlike openings.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modiiication,still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- Figurel is a vertical section of the front portion of a building constructedin accordance with and embodying the essential fea- Fig. 2 is a Viewsimilar to Fig. l of a modification. Fig. 3 is a front view. Fig. 4 isan enlarged section. Fig. 5 is a perspective view of a modified form ofmold for cornice or like finish. Fig. 6 is a section of the parts shownin Fig. 5, the dotted lines showing the upper part of the mold thrownupward to admit of the lower portion being readilydrawn down away fromthe cornice or like part.

Corresponding and like parts are referred `Application led April l0,1902. Serial No. 102,273.` (No model.)

to in the following descriptionr and indicated in all the views of thedrawings by the same reference characters.

The form comprises inclosing sides, the space being adapted to be filledby concrete or like material employed in the formation of artificialstone. The front side l and the inner side 2 are spaced apart a distancecorresponding to the thickness of wall desired and each is strengthenedand st'iened by Yposts 3 and 4, which are braced in any substantialmanner and tied by bolts 5 or like securing means. Planks or boards 6are secured to the posts 3,and corresponding planks or boards 7 areattached to the posts 4. These boards are jointed at their meeting edgesby matching tongue and groove of `any form which will retain the boardsin alinement and prevent escape of moisture. The inner faces of theboards are covered by sheet metal, as shown at 8, to prevent absorptionof moisture by the boards and a too-rapid drying out of the concretewhen setting. When the front of the building is to be laid o in blocksto represent stonework or other inish,ribs 9 project inward from thefront side l of the form, and these ribs 9 may be of any shape,according to the required form of joint Or groove to be impressed intothe front of the building. The ribs 9 may be an integral part of theboard 6 or may be strips attached thereto, and the faces designed tocome in contact with the concrete are protected by sheet metal,asindicated most clearly in Fig. 4.

The form is provided with openings correspondingto the window, door, andother openings of the building and is of such construction as to admitof its ready adaptation to the character of structure to be erected.Molds 10 and ll surround the openings in order to give a linish both tothe exterior and to the interior of the building, should the same bedesired. Obviously one or both of the molds 10 and 11 may be dispensedwith.

These molds l0 and 1l are preferably of sheet IOO struction and reducingthe amount of combustible material generally entering into theconstruction of a building. Molds 12 and 13 are included in the front 1of the form when it is required to embellish the front of the buildingat any required point or points, and these molds are preferablyconstructed of sheet metal and are attached to the posts 3,bracing-pieces being interposed between said posts and the molds tostii'fen the latter and preserve their shape. In case it be desired todecorate the lower portion of the wall of a room an inner mold, as 14,is provided, and where a molding and cornice is desired at the ceiling amold 15 is provided.

To give the accustomed cornice-finish to the top of the wall, a mold 16is provided and is braced by stays 17 and 18, projected outward from thesides 1 and 2. Angle-irons 19 connect the inner ends of the stays 17 and1S with the boards 6 adjacent to the mold 16. In the event of the moldhaving an undercut portion or cove, as shown in Figs. and 6, the stays17 and 18 are pivotally connected, as shown at 20, and upper and lowerparts of the mold 16 are separable to admit of the upper portion beingthrown u pward,as indicated by the dotted lines in Fig. 6, whereby thelower portion may be drawn from the cornice or work by a downwardmovement, thereby admitting of freeing the cove or undercut portion ofthe mold.

In buildings having the floors constructed of concrete, as shown mostclearly in Fig. 1, the inner side 2 of the form is left open to admit ofthe concrete forming the wall and the floor uniting and forming onehomogeneous mass. The cornice in the angle between the ioor and wallalso constitutes a bracket to support the door and brace the juncture ofsaid iioor with the wall, as will be readily comprehended. The concreteiioor is indicated at 21 in Fig. 1, and in practice is strengthened bywire-cloth, metal lathing, or iron rods 22, which likewise extend intothe space formed between the sides 1 and 2, so as to be ernbedded in thewall of the structure, thereby forming a firm bond and tie. The wall ofthe structure is likewise stiffened and braced by rods 23, beams or bars24 being provided at dierent point in the height of the wall to receivethe ends of the rods 23, which are connected thereto in any substantialway so as to form a stable structure. The bars or beams 24 extendlengthwise of the building and are preferably located at thefloor-lines, and the outer ends of the rods 22 are connected thereto.These parts or beams 24 may be of any shape such as commonly employed inthe construction of buildings.

In the class of buildings not required tol have iireproof or concretefloors the joists 25 have their beveled ends extended into the form, soas to become embedded in the concrete during the formation of the walls.This is indicated most clearlyv in Fig. 2. When the floors areconstructed of concrete, the ceilings may be suitably ornamented byproviding plates having the design impressed therein, said plates beingbraced from below bya suitable framework, such as commonly elnployed inthe construction of concrete iioors. In order that the molds and Variousornamentations may present a smooth and sharp finish, it is necessary toplaster the same in the wellknown manner, the body of the wall or iioorbeing filled in with ordinary concrete or like compositionconsisting,essentially,of cement, sand, stone, gravel, and the like.

j Having thus described the invention, what is claimed as new is- 1. Aform for the construction of buildings of cement and like material, thesame having openings in its inner side corresponding to the Hoor-linesof the building to admit of the fioors and walls merging or becomingunited, substantially as described.

2. A form for the construction of buildings of concrete and likematerial, the same having openings corresponding to the window, door andlike openings of the building, and a mold forming a side of the form andarranged adjacent to an opening thereof to provide a iinish to thecorresponding opening of the structure when completed, substantially asset forth.

3. A form for the construction of buildings of cement and like material,the same having openings corresponding to the openings of the building,and a mold surrounding an opening at each side to provide a finish tothe opening in the wall at both sides, substantially as set forth.

4. A form for the construction of buildings of cement and like material,and a mold extended from the inner side of the form adjacent to thefloor-line to provide a molding or cornice at the angle between thefloor and wall, substantially as set forth.

5. A form for the construction of buildings of cement and like material,comprising a mold projected from the outer side near the upper end toprovide a cornice, said mold comprising upper and lower movable parts toadmit of drawing the mold from the work after the latter has set,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
